Abstract
The present disclosure relates to the technical field of semiconductors, and provides a method of forming a photoresist pattern, and a photoresist structure. The method of forming a photoresist pattern includes: forming a photoresist structure on a target layer, where the photoresist structure includes a photoresist layer provided on the target layer, and an optical wave transmission layer provided on the photoresist layer; and performing exposure processing on the photoresist structure in a first medium, to form an exposure image in the photoresist layer, where the optical wave transmission layer is configured to improve lithographic resolution of the photoresist layer.
